I own a 2001 I30 with 43,000 thousand miles, recently purchased oxygen sensor at only Infiniti dealer in town for 216.00 dollars. Guess what, SES light turned itself off before I have had a chance to replace it. Great little car, I also own LS400 and RX300. Best to take it to a dealer for proper maintenance and fluids. There is no cheap way to care for motor vehicles properly. Being cheap will cost you in the long run.

I have a 2000 I30t Infiniti, which is giving me hell.

I replaced the ignition coil, then when I pulled the number 3 plug ignition wire out, the car shut off and will not keep running.

I finally got it back to where it was running rough. Idling there is no pulse on number 3 and 5 ignition coils. It's getting ground and constant 12 volts. The rest is getting pulse.

I jumped the wire direct from ECM - still no pulse.

HELP??? marday21@hotmail.com for contact

I have a 2001 Infiniti I30, and I really love the ride and the look of the car. I just had a new computer and all new wiring done last month on the car; this ran 1239.00.

A week ago the alternator suddenly went out sucking all the juice from my battery. I had a new alternator and new battery installed at over 700.00. This included a 60.00 tow to dealership and over two hours labor.

Today I noticed the battery light icon came on and went off, then came on again. I was wondering what could possibly cause this. The dealership told me to bring it by, and they would check it out for me. They seem to think it just may be a loose connection or wire. Any opinions on this.

I can't imagine there being anything electrical the matter after having everything replaced recently. The only thing I can see is possibly a loose connection.

I have an I30t 2000 Infiniti and the Sun Roof does not work. I cannot find the fuse to check if it is open. I checked the three fuse boxes under the hood and the one inside the passenger compartment. Any suggestions would be welcome on how to trouble shoot this or where the fuse may be hiding.

I got infiniti I30 2001 for my son just over a year ago. Lately the check Engine light comes on and goes off after a few days. I did check the engine diagnose O2 sensor code came up changed the O2S and days later the driver-side Seat won't move forward. And the check engine light is back on again. No more infiniti.

I own a 1998 Infiniti; very smooth riding vehicle. I have 165,000 miles. I change the oil regularly and just recently had the radiator flushed and a fuel injection cleaning. Don't think I even needed to do that; the car never runs hot, it doesn't leak oil or transmission fluid. Oh, by the way did I mentioned I haven't change the trans fluid yet, so far no problems with the trans. Now, with all that said, the check engine light now comes on and I have a blinking air bag light. I haven't diagnosed the problem yet, and the vehicle seems to run a little sluggish but OK. I'll be replacing the plugs for the first time, hopefully that will resolve the sluggish problem and the check engine light issue. Does anyone know what the blinking air bag light indicates?

I just bought a 2000 Infiniti I30. It has 117,000 miles now, Had 104,000 when I bought it 6 months ago. The fuel pump went out last week, replaced no problem. But the SES light will not stay off even after replacing the air sensors marked by the codes. The car runs but I hear a hum in the engine compartment area that sounds like the car seems to be trying to over-rev. Or that the cooling fan is running wide open. NOT sure. My mechanic says the codes should be clear as we have replaced the sensors. But we are still getting air sensor bad codes. At this point I'm thinking of selling this car. Just wondering if others are having this problem and if recalls were done for this problem. Does Infiniti support their products?

I have a 2000 Infiniti I30t. My service engine light went on and off a few times and took it to get it checked. The problem was the coils that sparked the engine to start. There are 6 of them which I saw someone else say. I've replaced one and it solved the problem. I was told they will all malfunction because between 2000 and 01 the coils from a certain manufacturer were all malfunctioning because of how they were made. My service engine light came on again but went away on its own and its been a few months since that and hasn't come on again. The car runs great and if the light comes on again it will probably just be the coil issue.

I have been driving my 2000 I30 since I bought it new in April 2000.

The SES light has been coming on and off intermittently for the past 4 or 5 years. First in 2004 it was off when I got smog checked, so it passed, then it came back on.

I had my local mechanic who has done only oil changes check the codes, and was told the ignition coils and catalytic converter codes P131 and P420 would need attention from the dealer.

The dealer replaced first 2 coils, then an additional 4 coils at $1200+ expense.

SES light kept coming back on.

Finally, the dealer agreed in April 2008 to replace the Bank 2 converter and reset the codes in time for current year smog check to pass. Then the SES light came back on and the 02 sensors needed to be replaced.

Fortunately, all of this was covered under the emissions 80,000/8 year warranty (just in time, car has only 40,000 miles).

Now in October '08, the SES light is back on and the code P420 indicates Bank 2 needs to be replaced again! Dealer checked and now claims that the Bank 1 converter and O2 sensors were replaced by mistake last April, so has replaced Bank 2. Will wait to see what happens next, but this definitely seems to be something that, given the multitude of similar instances among so many owners of 2000 I30, should be considered for recall. What will it take for Infiniti realize it is losing future customers over this? I was considering the M45 as my next car, but am extremely reluctant at this point.

I'm currently driving an Infiniti I30 2000. I've had this car since about February 2007. It was purchased, pre-owned. I was very pleased with this car in the condition it was in.

Over the years of owning this car, I've ran into a lot of problems - most of which has already been discussed here. I've been having electrical problems - had the alternator replaced twice, two new batteries... The "check engine" light won't go off. I've had it checked numerously. Had to replace the radiator, both axles, and the power steering hose... Took it to a Nissan dealership for super expensive repairs, air flow had to be replaced.

I recently took the car down to get it checked, and the code given was for the catalytic converter. Whether it's the sensors or it is seriously restricting the exhaust. It's strange how so many other people have ran into the exact, or even similar, problems with the Infiniti I30.

Is the car worth maintaining further, or is it time to look for a new car?
